The Nikons manual focus finders are bigger and brighter than the average DSLR. The Nikon F3 without the HP option is higher magnification (I have one) Mine has the Beattie intenscreen in it which is brighter again. Doug tells us that the SL finder is an order of magnitude superior again.

The F3 HP finder is pretty good, but not up to the standard of the R8/9 or the SL.
